I cannot open yahoo mail login page over wireless using FF 35.0

Question

Ever since FF updated to 35.0 I can not open yahoo mail log in,
using wireless. It seems to work only if plugged in. If I open it in IE 11 I seem to have no issues though regardless of how I connect. I have tried several of the suggestions safe mode, resetting, firewall, etc but no luck.
Running Win7 64 bit (with latest updates), Firefox v35.0

Okay, Using wired you have access, using wireless, none.
I take it both are going thru the same modem?
